Attachment No. A4

Public Input No. 46-NFPA 77-2016 [ Global Input ]

Type your content here ... Make universal change from "bonding and grounding" to "bonding orgrounding". While "grounding and bonding" is ok in some context it is not ok in all context becauseyou are either doing one, or the other, not both. When stating bonding or grounding you are good inany context. This would also apply to circumstances of bond and ground to bond or ground. I findmany people are confused and use these terms interchangably when discussing these actions eventhough both have there own destinct definition.

Statement of Problem and Substantiation for Public Input

Grounding means everything has the same static potential as earth. Bonding mean everything bonded has the same static potential. In most of the context the use of "and" can cause confusion.

Public Input No. 4-NFPA 77-2015 [ Section No. 7.4.1 [Excluding any Sub-Sections] ]

Bonding is used to minimize the potential difference between conductive objects, even where the resultingsystem is not grounded. Grounding (i.e., earthing), on the other hand, equalizes the potential differencebetween the objects and the earth. Examples of bonding and grounding are illustrated in Figure 7.4.1.

Figure 7.4.1 Bonding and Grounding.

7.4.1 A. (add definition (steps to) of pictures for bonding and grounding). 1. Top picture, first bond the fueltruck then, the forklift. 2. Middle picture, first ground the vehicles then connect to ground. 3. Bottom picture,First ground vehicles then, bond the fuel truck to the car. 4. B. Reverse the order to remove the bonding andgrounding. 1. Remove bond from fuel truck then, forklift. 2. Remove ground from earth then, vehicles 3.remove bond from car then, fuel truck. Then remove ground from earth then, vehicles.


It is my opinion that, Potential static discharge at the source of the greatest hazard could be reduced by grounding and bonding steps that take any potential static charge to the furthest point. If an arc were to occur it would be at the point of discharge and not at the point of potential danger (at the vehicle...)

Public Input No. 43-NFPA 77-2015 [ Section No. 9.2.1.4(C) ]

(C)

It is emphasized that bonding the tank to the fill stem is not sufficient; a majority of recorded explosionshave occurred when it was believed the tank had been adequately bonded. The electrostatic potential thatis responsible for the spark exists inside the tank on the surface of the liquid and cannot be removed bybonding. Measures to reduce this charge can be one or more of the following:

(1) Avoid spark promoters. Conductive objects floating on the oil surface increase the charge of sparkingto the tank wall. Metal gauge rods or other objects projecting into the vapor space can create a sparkgap as the rising liquid level approaches the projection. A common precaution is to require that fillpipes (downspouts) reach as close to the bottom of the tank as practicable. Any operation such assampling, taking oil temperature, or gauging that involves lowering a conductive object through anopening into the vapor space on the oil should be deferred until at least 1 minute after flow has ceased.This will permit any surface charge to relax.

(2) Reduce the static generation by one or more of the following:

(3) Avoid splash filling and upward spraying of oil where bottom filling is used.

(4) Employ reduced fill rates at the start of filling through downspouts, until the end of the spout issubmerged. Some consider 3 ft/sec (0.9 m/sec) to be a suitable precaution.

(5) Where filters are employed, provide relaxation time in the piping downstream from the filters. A

relation

(a) relaxation time of 30 seconds is considered by some to be a suitable precaution.

(6) Eliminate the flammable mixture before switch loadings by gas freeing or inerting.

[30: A.28.11.3]


Use of the term "relaxation" in place of "relation" avoids confusion.

F.3.1

Liquids that have relaxation time constants ranging from 0.36 sec down to 0.002 sec (equivalent to a

conductivity range between 50 pS/m and 104 pS/m for typical hydrocarbons having dielectric constants ofabout 2) are considered conductive semiconductive . Examples include crude oil and butyl acetate.


This is a correction to the term "conductive". The section is about semiconductive liquids.
